Adjust properties of AudioSource created with PlayClipAtPoint

What up UA, quick question. Recently discovered “PlayClipAtPoint”, which is super handy. However I want to set the volume/pitch/etc. of the AudioSource that is created. Is there a simple way to do this?

(I don’t fully understand exactly what criterion PlayClipAtPoint uses to generate the temporary AudioSource.)

Thanks so much!

PlayClipAtPoint creates a temporary game object called “One shot audio” that contains the AudioSource, and destroy it when the sound finishes. Unfortunately, it doesn’t give us any reference to the object created - shame on you, Unity: PlayClipAtPoint should return a reference to the AudioSource, or at least to the object created!

An alternative could be to find the temporary object with GameObject.Find(“One shot audio”), but this would fail if more than one “One shot audio” existed. But there’s a solution: create your own PlayClipAtPoint function, like this:

function PlayClipAt(clip: AudioClip, pos: Vector3): AudioSource; {
  var tempGO = GameObject("TempAudio"); // create the temp object
  tempGO.transform.position = pos; // set its position
  var aSource = tempGO.AddComponent(AudioSource); // add an audio source
  aSource.clip = clip; // define the clip
  // set other aSource properties here, if desired
  aSource.Play(); // start the sound
  Destroy(tempGO, clip.length); // destroy object after clip duration
  return aSource; // return the AudioSource reference

You can set other AudioSource properties inside PlayClipAt, or use the returned AudioSource reference to access these properties in the calling code, like this:

  var sound = PlayClipAt(someClip, transform.position);
  sound.pitch = 1.5;
  sound.volume = 0.5;

Here’s a quick and dirty adaptation to allow the passing of AudioSource Objects into the mix so that you can copy the properties. This may be helpful in certain situations where you want to be able to assign an AudioMixer as well as adjust other properties within the inspector:

// copies audiosource properties to temp audiosource for playing at a position
    public static AudioSource PlayClipAtPoint(AudioSource audioSource, Vector3 pos)
        GameObject tempGO = new GameObject("TempAudio"); // create the temp object
        tempGO.transform.position = pos; // set its position
        AudioSource tempASource = tempGO.AddComponent<AudioSource>(); // add an audio source
        tempASource.clip = audioSource.clip;
        tempASource.outputAudioMixerGroup = audioSource.outputAudioMixerGroup;
        tempASource.mute = audioSource.mute;
        tempASource.bypassEffects = audioSource.bypassEffects;
        tempASource.bypassListenerEffects = audioSource.bypassListenerEffects;
        tempASource.bypassReverbZones = audioSource.bypassReverbZones;
        tempASource.playOnAwake = audioSource.playOnAwake;
        tempASource.loop = audioSource.loop;
        tempASource.priority = audioSource.priority;
        tempASource.volume = audioSource.volume;
        tempASource.pitch = audioSource.pitch;
        tempASource.panStereo = audioSource.panStereo;
        tempASource.spatialBlend = audioSource.spatialBlend;
        tempASource.reverbZoneMix = audioSource.reverbZoneMix;
        tempASource.dopplerLevel = audioSource.dopplerLevel;
        tempASource.rolloffMode = audioSource.rolloffMode;
        tempASource.minDistance = audioSource.minDistance;
        tempASource.spread = audioSource.spread;
        tempASource.maxDistance = audioSource.maxDistance;
        // set other aSource properties here, if desired
        tempASource.Play(); // start the sound
        MonoBehaviour.Destroy(tempGO, tempASource.clip.length); // destroy object after clip duration (this will not account for whether it is set to loop)
        return tempASource; // return the AudioSource reference
